Why “multi-welding”? Because this welding transformer (WT) has many important additional functions. Whereas in a traditional welder whose core is assembled from E- and I-shaped laminations there is often no room to squeeze in even one or two auxiliary turns, in the proposed donut-shaped design there is more than enough free space. As a result, Read more…
For many operations performed in training workshops and technical clubs, a portable universal tool similar to a dental drill would be very convenient. However, it is almost impossible to buy such a device, and as always in such cases, the question arises: is it possible to make something similar with your own hands? The main Read more…
In technical hobby clubs there is often a need for wooden workpieces with an even, smooth surface. Getting a well‑sanded board is not easy: hand processing is labor‑intensive and requires certain skills. The machine designed in the rocket and space modeling laboratory of the Kazakhstan Young Technicians’ Station makes it possible to mechanize the sanding Read more…
The compressor unit may not be as essential in a home workshop or a car enthusiast’s garage as an electric drill or a vise. However, when such a unit is available, it greatly simplifies some labor‑intensive operations (such as inflating tires) and can significantly improve the quality of work (for example, when spray‑painting parts). Wherever Read more…
No matter how good a tool or even a machine a home craftsman has, drilling a hole accurately or machining a workpiece properly while holding it with pliers, let alone in one’s hands, is frankly impossible. That is why any home workshop, even a beginner’s, includes a vise. True, this useful device is not always Read more…
For high-quality and fast painting with airbrushes and spray guns, for many other jobs in a home workshop, a desktop mini-compressor that can be assembled from a refrigerator compressor unit is suitable. Moreover, it is not at all necessary to use a new unit: one with clogged pump valves will do just fine. The main Read more…
At first, like most beginner radio amateurs, I drilled the mounting holes in printed circuit boards with a universal tool — an electric hand drill. However, it turned out that for making small holes (less than 3 mm in diameter) and with high accuracy, a hand drill is a poor assistant. After breaking quite a Read more…
In the household there is occasionally a need for longitudinal sawing of long boards into beams or battens, trimming chipboard (particle board) to size, or performing similar operations with other comparable building or furniture materials. Anyone who has done such work with a hand saw knows how tedious and laborious it is, especially when several Read more…
A jigsaw is a common tool. However, when working with it, one often runs into certain difficulties: the blade breaks, slips out of the clamps, and when cutting along a curved contour it often twists, which makes it hard to keep the desired direction. It is much more convenient to use an electrothermal (hot-wire) jigsaw, Read more…
Wood burning is very often used for finishing wooden items. Even when this operation is done with a special tool—a pyrograph—it is very labor-intensive, especially when applying various complex ornaments. I would like to suggest a successfully tried mechanized method of burning complex patterns and various appliqués. It is much more productive than the traditional Read more…
